Keeping the party together when Matchmaking

Same issue with keeping all members of the party together when matchmaking.  Doesn't matter which of the 3 of us (all on Xbox with cross-play enabled for all) are the party leader and who gets "left in the lobby" is also random.  Sometimes, it's even the party leader.  It has even thrown all 3 of us in completely separate matches. We've reformed the party. closed the game, and even cleared our respective caches (via hard reboot), and the bug continues to happen randomly.  It has been occurring since the beta and continues to this day.  EA, please correct and upload an update.  Thanks.
